To all whom it may concern:

Be it known that I, Jnnvrs R. HAaBEcK, a citizenof the United States, residn at Detroit, in the county of Wayne and tate of Michigan, have invented a new and useful Container-Closure, of which the following is a specification.

This invention relates to asealing-gasket for cans, pails, and other containers intended for the shipment of canned fruits and ve etables, paints, oils, &c, and the object o my invention is to provide means whereby the closure of a container-top may be rendered fluid-tight without the use of solder orcement.

My invention consists of a closure having a cylindrical portion and a flat ilange, a cap'- s aped asket of fibrous material for the closecured to the same and a head for the container having a cylindrical flange, the parts being so pro ortioned that the material of the gasket w1 l be tightly wedged in between the closure and the flange on the head when the arts are assembled.

It furt er consists in tapering the lower end of the c lindrical Iortion of the closure so as to allor space inside of the liange on the head wherein a ortion of the gasket may swell ou account of a sorbing a portion of the liquid contents of the container, thereby forming a In the accom anying drawings, which illustrate an ambo ent of my invention, Figure l isa central cross-section of a container rovided with my improved seal and F` 2 1s aplan of the container on a slightly-smblcr sca e.

Similar reference characters refer to like parte throu hout the several views.

Closures or containers intended for liquids are usually either soldered down or rovided with a screw or other mechanical evice to insure a liquid-tight joint, These construetions are unsatisfactory, the soldered top be-Y cause of the troubleof cutting the material to open the container and the mechanical device because of the expense.

I In the'construction here shown the body l may be of any suitable material, either of tin or of fiber, and the bottom 2 vis secured thereto by soldering or crimping, as desired. The sheet-metal head 3 is also 'secured to the bodv in any desirable manner and is provided with an upwardly-projecting bead 4 and a downwardly-extending cylindrical flange 5. The closure is made u of the 'disk 6, a tapering portion 7, a straig t cylinder 8, a flat flange 9, and an inturned portion 10. The gasket 11 for the closure 1s preferably of ve etable parchment, aper, or similar materia and is adapted to t tightly over the closure, being hel in place by the inwardly-turned portion 10 of the closure.

The head 3 may be formed by one stroke of the die. The closure is cut out as a disk, as is also the gasket. The two may then be formed at the same time by lacing one on the other in the die; but preibrably each is formed se arately, the portion 10 of the closurebeing eft flat. The gasket is then slipped onto the closure and the part 10 of the closure crimped down.

When the container has been' filled the closure is forced into the opening in the head,

between the flange 5 and the cy Inder 8 of the closure. As soon as any of the exposed portion of the gasket is moistened by the liquid in the container the fibrous material will swell, still further insuring a lfluid-tight joint, especially in the ta ering space formed between the part 7 of t e closure and the Bange 5. When the closure is forced down into place, a ortion of the gasket will also be compressed Ibetween the bead 4 of the head and the flange 9 of the closure, thus assisting in forming a fluid-tight joint.

Havm now explained my improvement, what I c aim as In invention, and desire to secure by Letters atent, is-

1. In a container, the combination of a head having a downwardlyxtending cylin-` drical flange and araised circular bead adjacent thereto, a closure comprising a c lmdrical portion having a ta ering end c osed l liet radial flange, and an absorbent fibrous I gasket secured to said closure and adapted the material of the gasket bein compressed by a clrculardisk and a at outwardly-ex to be compressed between the cylindrical portion of the closure. and the cylindrical flange of the head.

3. Inv a container, the combination of a head having a cylindrical ange, a closure comprising a'cylindrical portion closed at one end and having a radial ange at the other andafibrousgasket ada ted to becom ressed between the cylindrica portion of t e cl'osure and the cylindrical flange of the head.

4. A closure for containers comprising a cylindrical body closed at one end and hmnngl 5. In a container, the combination of a head having a downwardly-extending cylindrical ange, a closure com rising a cylindrical portion closed b a dlsk at its lower end land an absorbent brous asket secured to the closure and compresse between the cylindrical portion of the closure and the cylindrical flange of the head and adapted to eX- and between the free edge of the cylindrical e of the head and the closure to form a iui -tight joint.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
